Windows doesn't load: Invalid EFI File Path

**Cuithinien** · March 13th, 2013

I installed Linux Mint, and in the process removed Windows 7 (the C:\ drive was corrupted). I had a backup, fortunately, so I reformatted the drive and restored the backup. Linux Mint recognizes the drive and all its files, GParted says it's a-ok, and GRUB recognizes it as an operating system. But when I try to boot to Windows 7, it spits out "Invalid EFI file path". Now, this seemed similar to this thread's situation, so I ran bootinfoscript (post 4), which gave this:

Code:

============================= Boot Info Summary: ===============================


 => No boot loader is installed in the MBR of /dev/sda.
 => Grub2 (v1.97-1.98) is installed in the MBR of /dev/sdb and looks at sector 
    1 of the same hard drive for core.img. core.img is at this location and 
    looks in partition 2 for /boot/burg.

I lost the thread (no pun intended

) from there. Any ideas?

You have mixed UEFI and BIOS boot.

Windows on sdb is configured for BIOS boot and MBR(msdos) partitioning.
Your sda has an efi partition with gpt partitioning and is trying to use UEFI to boot.
Ubuntu will boot from gpt partitioned drives in BIOS mode, but needs a tiny 1MB unformatted bios_grub partition not the efi partition. But how you install is determined by how you boot installer. If you boot installer in UEFI mode it installs in UEFI.

Windows only boots in UEFI mode from gpt partitioned drives.
Windows boots from MBR drives in BIOS or legacy mode.

Thanks for the response. So, from what I understand, my HDD and SSD are formatted differently and are therefore incompatible?
More importantly, what can I do? If I reformat the drive, how do I avoid this error again?

**oldfred** · March 14th, 2013

While I now prefer gpt partitioning, you need to convert your SSD from gpt back to MBR and reinstall Linux in BIOS/MBR mode. With both systems is BIOS mode you should not have any issues.

How you boot installer is how it installs, so be sure to boot in Legacy/BIOS/CSM mode not UEFI mode to install Linux.

You may be able to convert, but that may not be easier than a new install?

You then need to use gdisk to convert from gpt to MBR

Thanks! I'll do that. But if possible, can you explain (or give a link that explains) what exactly UEFI, MBR, GPT, CSM, and BIOS are? I'm confused.
P.S. On second thought, should I post this in the beginners' forum?

**oldfred** · March 14th, 2013

Some links:
gpt(GUID) and MBR(msdos) are two ways to partition a drive.
The MBR is the first sector of a hard drive that a BIOS uses. BIOS determines hardware and then jumps to MBR to start to boot a computer.
UEFI is a new replacement for BIOS, but has a BIOS mode also also known as CSM. UEFI looks into efi partition for more boot code.
Compatibility Support Module (CSM), which emulates a BIOS mode

Thanks. I used gdisk to change /dev/sdb (the Windows disk) to GPT, but the same error still happens. My BIOS is UEFI-capable, and Windows 7 should boot from a GPT disk. But that doesn't seem to have anything to do with the "Invalid EFI file path" error. Ideas?

You cannot just convert Windows to UEFI boot. Not sure of all the details but it has to have some unformatted space in the partition just before the main Windows install and you have to have an efi partition, usually first, but many Windows installs have a repair partition or recovery partition first. It is a lot of change. It may be easier just to reinstall in UEFI mode. You have to boot installer in UEFI mode.

Even with Ubuntu you have to convert from BIOS boot to UEFI boot. It primarily is changing boot loader from grub-pc(BIOS) to grub-efi (UEFI) and editing fstab to use efi partition.

Microsoft suggested partitions including reserved partition for gpt & UEFI:
